Taking Halo-independent dark matter methods out of the bin
We develop a new halo-independent strategy for analyzing emerging DM hints, utilizing the method of extended maximum likelihood. This approach does not require the binning of events, making it uniquely suited to the analysis of emerging DM direct detection hints. It determines a preferred envelope, at a given confidence level, for the DM velocity integral which best fits the data using all avai...
متن کاملHalo-independent methods for inelastic dark matter scattering
We present halo-independent methods to analyze the results of dark matter direct detection experiments assuming inelastic scattering. We focus on the annual modulation signal reported by DAMA/LIBRA and present three different halo-independent tests. First, we compare it to the upper limit on the unmodulated rate from XENON100 using (a) the trivial requirement that the amplitude of the annual mo...
متن کاملDid VV 29 collide with a dark Dark-Matter halo?
Westerbork Radio Synthesis Telescope observation of the galaxy VV 29=Arp 188=UGC 10214 shows that there are at least three distinct dynamical components whose kinematics can be traced in 21cm line emission. The system appears to be the result of a galaxy-galaxy interaction. We identify a sufficient number of dynamical elements containing baryons (stars and neutral gas) that there is no compelli...
متن کاملWeighing the Dark Matter Halo
The dark matter problem will be solved only when all of the dark matter is accounted for. Although wimps may be discovered in direct detection experiments soon, we will not know what fraction of the dark matter halo they compose until we measure their local density. In this talk, I will offer a novel method to determine the mass of a wimp from direct detection experiments alone using kinematica...
متن کاملThe Indirect Detection of Halo Dark Matter
High energy particles are produced by the annihilation of dark matter particles in our galaxy. These are presently searched for using balloon-borne an-tiproton and positron detectors and large area, deep underground neutrino telescopes. Dark matter particles, trapped inside the sun, are an abundant source of such neutrinos. From both the cosmological and particle physics points of view the ligh...
